LlFTlNG-JACK FOR SPIKING RAILWAY-TIES.

SPECIFICATION forming part of Letters Patent NO. 795,195, dated July 18, 1905.

Application filed May 1, 1905. Serial No. 258,244.

To (all whom, it may concern.-

Be it known that I, GIROLAMO CoMI, a citi- Zen of the United States, residing at Cobalt, in the county of Middlesex and State of Connecticut, have invented a new and useful Improvement in Lifting-Jacks for Spiking Railway-Ties; and I do hereby declare the following, when taken in connection with the accompan ying drawings and the figu res of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a side view ofa lifting-jack for spiking rail way-ties constructed in accordance with my invention and shown as applied to a rail and connected to a tie; Fig. 2, a top or plan view of the same; Fig. 3, a sectional view on the line a I) of Fig. 1.

This invention relates to an improvement in lifting-jacks for spiking railway-tiesthat is, a device for holding the rails in close contact with the ties or for lifting the tie up into close contact with the under edge of the rail and holding it there so that it may be spiked, the object of this invention being a simple arrangement of parts whereby a device is produced which may be readily operated by one man; and the invention consists in the construction as hereinafter described, and particularly recited in the claims.

In carrying out my invention I employ a flat bed-plate 2, corresponding in width substantiall y to the width of the top face of a railwayrail and provided at each side near its outer end with a downwardly-projecting lip 3. At its rear end the plate is bifurcated, forming two bearings 4 5 for a transversely-arranged shaft 6, which at one side projects beyond the edge of the bed-plate. On this shaft is a cam 7, which is provided with an operating-handle 8, by which the cam may be turned upon the shaft 6. From one side of the bed-plate depends an arm 9, having a finger or end 10 extending inward to bear upon the web 11 of the rail, while upon the opposite side of the bed-plate is pivoted a latch 12, the end of which bears upon the opposite side of the web 11. This latch at its upper end has a tail 13,

upon which rests a spring 14, which is pivoted to the top face of the plate 2, near the outer end thereof, the tendency of the spring being to hold the latch in its open or closed position. Preferably and as herein shown the latch will be provided with a handle 15, by which it may be conveniently turned. Mounted on the outer end of the shaft 6 are links 16 and 17, to the ends of which are pivoted the upper ends or arms 18 and 19 of dogs 20 and 21, which dogs are pivoted together, as at 22, each dog being provided with a hook-like point 23.

To place the device in position upon the top of the rail, the latch 12 is opened so as to permit the bed-plate to be placed upon the top surface of a rail with the lips 3 extending on opposite sides thereof. By opening the latch 12 the arm 9 is permitted to pass down over the upper edge of the rail and the end 10 thereof bear against the web 11. When thus placed, the latch 12 is turned so that its end engages with the opposite side of the said web, the spring 14 holding it in this position. The handle 8 is then turned backward, as shown in Fig. 1, so as turn the cam 7 substantially out of contact with the face of the rail. The dogs 20 and 21 are passed on opposite sides of a tie 245, and the points 23 of the dog are engaged with the sides thereof. The handle 8 is then raised, turning the cam 7, so as to lift the links 16 and 17 and draw the ends 18 and 19 of the dogs toward each other, which force the, points 23 into the tie and lift the tie upward against the under face of the rail. When thus raised and held in position, spikes may be driven in the tie at the side of the rail opposite the dogs, and as the spikes are driven home the cam may be further turned, so as to take up for any play which i might exist when the spike is finally driven home. spiked, the device is reversed in position and the other side spiked, and then the device moved to the next tie, and so on. This device is readily operated by. one man, and the cam 7 is so formed as to be self-holding, so that the man operating the device may also drive the spike, as no otherassistance will be required.

Having fully described my invention, what WVhen one side of the railis I claim as new, and desire to secure by Letters Patent, is-

1. A lifting-jack for spiking railway-ties, comprising a bed-plate, a shaft mounted at one end thereof, a cam on said shaft and adapted to bear upon the upper face of the rails, links mounted on said shaft, and dogs pivoted to gether and connected at their upper ends With said links, substantially as described.

2. A lifting-jack 't'or spiking railway-ties, comprising a bed-plate provided at its outer end With lips and at its opposite end with a transversely-arranged shaft, a cam on said shaft and adapted to bear upon the upper-face of the rail, links mounted on said shaft, and two dogs pivotall connected together and with said links, substantially as described.

3. A lifting-jack for spiking railway-ties,

comprising a bed-plate, an arm on one side of said plate, a latch pivoted to the opposite side of said plate, said arm and latch adapted to engage With the Web of the rail, a transverselyarranged shaft at one end of said plate, a cam GIROLAM O COMl.
